We have installed the new SonarQube LTS version 6.7.5. Its works fine accept on one thing the project search wil not display this new project in the search results. Some other projects have the same problem. Direct links are working fine but we can’t search this project in de search bar.

This is most likely because of and outdated/corrupted ElasticSearch index. In standard operating, upgrade included, the ES index is always kept up to date by SonarQube, so there is nothing to handle for it. But sometimes with “less standards” operations, it could be corrupted.
